摘要： To reduce the time for writing a voltage onto a gate of a driving transistor. In an initialization period, a node B is fixed to an initial voltage VINI, transistors are turned on, and a current flows into an OLED element, such that a voltage according to the current is held at the node A. Thereafter, the transistors are sequentially turned off, such that a threshold voltage of a driving transistor is held at the node A. In a writing period, a transistor is turned on and a data signal X-j is supplied, such that a voltage of the node B varies by the amount according to the current flowing into the OLED element. The voltage of the node A varies from the threshold voltage by the amount which is obtained by dividing the voltage variation by a capacitance ratio. In a light-emitting period, the transistor is turned on, such that a current according to the voltage of the node A flows into the OLED element.

摘要： To reduce time for writing a target voltage in the gate of a driving transistor. In a first period, a transistor 211 is switched on to allow a driving transistor 210 to function as a diode and transistors 212 and 213 are switched on to electrically connect the drain of the driving transistor 210 to a data line 112, to which an initial voltage is applied, such that the initial voltage is applied to the gate of the driving transistor 210. In a second period, a transistor 212 is switched off such that the gate of the driving transistor 210 is maintained to have an off voltage corresponding to the power source. In a third period, the transistor 211 is switched off such that the voltage of the data line 112 is converted into a grayscale voltage to maintain the gate of the driving transistor at the target voltage. In a fourth period, the driving transistor 210 flows the current corresponding to the maintained gate voltage to an OLED element 230.

摘要： To reduce a time for applying a target voltage to a gate of a driving transistor. During an initializing period, both ends of a capacitive element become a short-circuited state by turning on transistors, so that node A and B becomes a voltage made by subtracting the threshold voltage Vthp of the driving transistor from a power source voltage VEL. During a writing period, the transistor is turned on and a data signal X-j is supplied to change the voltage at the node B as much as a voltage corresponding the current which is to flow into an OLED element. The node A is changed from the threshold voltage as much as the value obtained by dividing the voltage change by capacity ratio. During a light-emitting period, the transistor is turned on, so that the current corresponding to the voltage at the node A flows through the OLED element.
